Abstract
A pocketed spring comfort layer for a bedding or seating product has pockets characterized by the individual mini coil springs of the comfort layer being pocketed with between at least one cushion assembly and a sheet of polypropylene fabric. Each cushion assembly includes at least one foam layer. A segmented seam joins the cushion assembly and the sheet of polypropylene fabric around each of the mini coil springs of the pocketed spring comfort layer. The method of making the pocketed spring comfort layer includes compressing the mini coil springs and creating pockets with a welding horn and an anvil.
